The patient was a 53 year-old male who had 3 syncopal episodes over a 6-month period. In the electrophysiological study, ventricular fibrillation (VF) was repeatedly induced by the ventricular extrastimulus method. Intravenous pilsicainide was administered, and the J-point and ST-segment in the right precordial leads became slightly elevated just following drug administration. Five min later, the patient experienced severe nausea and then vomited twice, at which point the electrocardiogram (ECG) showed increased elevation of the J-point and ST-segment. These ECG changes recovered to normal 30 min later. The cause of his syncope was strongly suspected to be related to the VF associated with Brugada syndrome. An interesting aspect of this case was the particular type of J-point and ST-segment elevation that was induced when the patient experienced nausea and vomiting. It is proposed that this phenomenon originated from the vagal stimulation associated with the nausea and vomiting.

Prevalence and Clinical Significance of Early Repolarization in Athletes: A Systematic Review.
Ann Noninvasive Electrocardiol
January 2025
Department of Internal Medicine, College of Medicine, Prince Sattam Bin Abdulaziz University, Alkharj, Saudi Arabia.
Introduction: Early repolarization (ER) is an electrocardiographic pattern characterized by J-point and ST-segment elevation, frequently observed in athletes. Initially deemed benign, recent studies suggest a possible association between ER and increased risks of cardiac arrhythmias and sudden cardiac death, necessitating a thorough examination of its clinical implications in athletes.
Methods: A comprehensive literature review was conducted using MEDLINE (via PubMed) and EMBASE databases, focusing on articles related to ER in athletes.
Background: Although intracoronary electrocardiography (IC-ECG) offers direct electrophysiological insights into myocardial ischemia caused by insufficient coronary blood supply, compared to common diagnostic methods like electrocardiography (ECG), it lacks widespread adoption and robust clinical research.
Objective: To analyze the value and accuracy of intracoronary electrocardiogram in myocardial ischemia diagnosis in coronary heart disease patients.
Methods: Three hundred patients treated at our hospital were included in the study.

Background: Precordial Bipolar Leads (PBLs), Weighted Unipolar Leads (WUL), and Regional Vectorcardiograms (RVCGs) are constructed using the same data recorded by a standard 12‑lead ECG, but they provide additional information not visible in the standard 12‑lead ECG (ECG) tracings.
Objectives: In previous studies during balloon occlusion of the LAD and RCA, we observed a complete ischemic inversion of the QRS waves, with folding of the loop and ST segment shift. In the present study, we aim to investigate this abnormality using new ECG methods.

Centro de Investigaciones Médicas Florida, Buenos Aires, Argentina (MJML) and Lankenau Institute for Medical Research, Wynnewood, PA, USA.
Background: Precordial Bipolar Leads (PBLs) provide new electrocardiographic information derived from standard 12‑lead ECG recordings.
Objectives: To explore the usefulness of PBLs in patients with acute circumflex coronary artery (CxCA) occlusion.
Methods: Twelve patients undergoing elective percutaneous transluminal coronary angioplasty (PTCA) were studied before and after acute CxCA occlusion and their data were processed with new methods based on PBLs.
Aim: To evaluate the features of ST-segment elevation myocardial infarction with the Aslanger pattern in comparison with traditional forms of inferior myocardial infarction in metabolic syndrome.
Material And Methods: This study included 30 patients with inferior myocardial infarction in the presence of metabolic syndrome: 9 patients with the Aslanger electrocardiographic pattern (group 1, age 59.7 [58.
